This invention relates to a system, apparatus, and/or method of retrofitting commercially available helmets to accommodate wired or wireless electronic systems. More specifically, the invention relates to of retrofitting commercially available helmets to accommodate wired or wireless electronic systems to enhance comfort, impact performance of the helmet, and battery longevity.
The incorporation of electronic communication modules (ECM), e.g., a one-way radio, into athletic helmets and/or other protective gear has been a recent popular development. Incorporating an ECM into an athletic helmet can offer many advantages to an athlete/player, such that they can allow the athlete to perform multiple functions at the same time, including the ability to intermittently and/or continuously view information presented visually by a display; potentially provide safety or help prevent injuries; increases field of view to observe the surrounding environment and the field of play; and/or allows “real-time” communication with coaches that sit on the sidelines.
However, the current methods of coupling or securing ECM into athletic helmets are not optimal because they may affect the safety of the player. Such non-optimal coupling or securement methods are often inconsistent or haphazard because (1) layout of each commercially available helmet varies making the securement complicated to figure out; (2) the experience and skill of the game-day equipment coordinator varies; (3) the tools and equipment (i.e., Velcro, tape, etc.) available for each team varies; (4) the size and fit of the helmet on the player varies; and/or any combination thereof. This leads to the helmets potentially becoming unsafe to wear due to direct contact of ECM to the head of player, the impact performance of the helmet may be affected, helmets become heavy and bulky, the helmets can have unequal distribution of weight, the system component can make the helmet awkward to wear and potentially provide unacceptable stress on the player's neck or head, the ECM may become more prone to damage, the system requires teams to keep extra ECM back-ups with their respective batteries in case of malfunctions or injury to players, and/or the system components require game-day coordinators to continuously confirm function resulting in significant time and effort, and potential waste of tools and equipment.
Consequently, there is a need for an improved helmet design that allows quick installation or coupling of various types of ECM components within a commercially available helmet to minimize many of these potential problems to the player. More specifically, such improved helmet design may be customized to the specific ECM, and its protective enclosure may also be small, lightweight, durable and/or low-profile, but yet not sacrifice comfort and impact performance of the helmet.

Methods of Retrofitting a CA Helmet into ECM Helmet
As previously disclosed herein, the improved ECM Helmet System can be employed to retrofit or modify a commercially-available (CA) helmet by removing at least a portion of the CA helmet's outer layer, impact mitigation and/or comfort liner to create a pocket or chamber, where a protective enclosure may be removably connected or removably disposed within the pocket or chamber. The protective enclosure may incorporate a cavity that can house at least one electronic communication modules (ECM) or at least one impact mitigation pad. The protective enclosure may desirably incorporate impact mitigation structures and at least one foam layer. The impact mitigation structure may desirably match the CA helmet impact mitigation layer. Conversely, a different impact mitigation structure may be used.
The term “retrofitting” or “modification” of an existing, commercially available helmet (CA helmet) into an electronic communications module helmet (ECM helmet) may require modifications to at least one of the CA helmet outer layer, the CA helmet Impact mitigation layer, and/or both the CA helmet outer layer and the CA helmet Impact mitigation layer. Such modifications may be “minor” or “major.” “Minor CA helmet modifications” is defined as using methods or mechanisms that add or remove at least a portion of the CA helmet outer layer and/or at least a portion the CA helmet impact mitigation layer that do not significantly affect the durability and/or the performance of the CA helmet to a significant degree. “Major CA helmet modifications” is defined as using methods or mechanisms that add or remove at least a portion of the CA helmet outer layer and/or at least a portion the CA helmet impact mitigation structure that significantly affects the durability and/or the performance of the CA helmet to a significant degree.
In one embodiment, the method to retrofit an existing CA helmet into an ECM may include the removal of the CA helmet comfort liner to position a protective enclosure within the CA helmet impact mitigation layer as shown in
In another embodiment, the method to retrofit an existing CA helmet into an ECM may include the removal of the CA helmet outer layer to position a protective enclosure within the CA helmet impact mitigation layer as shown in
In another embodiment, the method to retrofit an existing CA helmet into an ECM may include the removal of the CA helmet comfort liner for “position-specific” placement within the CA helmet impact mitigation layer as shown in
In another embodiment, the method to retrofit an existing CA helmet into an ECM may include the removal of the CA helmet outer layer for “position-specific” placement of a protective enclosure within the CA helmet impact mitigation layer as shown in
In another embodiment, the method to retrofit an existing CA helmet into an ECM may include the removal of a least a portion of a CA helmet comfort liner to position a protective enclosure within the CA helmet outer layer or the CA helmet comfort liner as shown in
Coupling or securing as described herein may include the same mechanisms or methods used to reattach the CA comfort liner to the CA helmet as originally designed or a different mechanism may be used. All coupling mechanisms that may be used may be known in the art, including press-fit, friction-fit, snaps, Velcro, magnets, adhesives, molding, sintering, welding, cam locks, screws and bolts, dovetail, interlocking protrusions (e.g. LEGOs) and/or any combination thereof. Each of these coupling mechanisms may utilize existing features of a CA helmet or may require minor modifications with penetration through at least one of the CA helmet outer layer, CA helmet inner layer, the CA impact absorbing layer, and/or any combination thereof.
Selecting CA Helmets for ECM Helmet Systems
It's understood that virtually any CA helmet from any manufacturer may be selected for retrofitting for improvement and manufacture of the ECM Helmet System. The CA helmet may comprise various helmets used in one or more athletic activities such as football, baseball, bowling, boxing, cricket, cycling, motorcycling, golf, hockey, lacrosse, soccer, rowing, rugby, running, skating, skateboarding, skiing, snowboarding, surfing, swimming, table tennis, tennis, or volleyball, any training sessions related athletic activities thereto, and/or any combination thereof.
Each of these various CA helmets may utilize similar basic standard features of a helmet design, but can significantly differ on the type of impact mitigation layer technologies.
In one example, the impact mitigation layers within the CA helmets can vary significantly because of the different technologies used.
In another example,
In another example,
In another example,
In another example,
It should be understood that these specific CA helmets are merely exemplary embodiments, and the retrofitting or modification could be utilized with virtually any helmet design from any manufacturer (which all helmet designs of different configurations are representative of a “CA helmet”). Of course, such retrofitting or modification of the CA helmet outer layer, Impact mitigation layer and/or the comfort liner may have a varying level of difficulty that may produce ECM helmets with varying results, but ECM helmets will continue to maintain safety and performance certification as required by the respective athletic governing body.
Identification of Regional Location with or without Assessment of Player Factors
In one embodiment, choosing or Identifying the proper regional location to retrofit a pocket or chamber Into the Impact mitigation layer of a CA helmet may be performed without assessing player factors. Other general factors for the desired regional location may include random selection, ease of placement, regional location where impact performance will not be affected, or reducing/eliminating structural modifications to CA helmet may be significant general factors in deciding which regional location that a pocket or chamber may be performed.
For example, it may be desired to select the front 210 or back-lower 260 regional location because of its ease of access and/or the reduction/elimination of the need for any potential structural modifications to the CA helmet 280.
In another example, it may be desired to select the jaw flap regional location 340 because of Its ease of access and the reduction/elimination of any potential structural modifications to the CA helmet 280 as shown In
In another embodiment, choosing or Identifying the proper regional location to retrofit a pocket or chamber into the Impact mitigation layer of a CA helmet may be performed with assessing player factors. Such assessment of the player factors may allow the manufacturer of the ECM helmet to predetermine the best regional location for a protective enclosure to be secured and/or enhance the impact protection that may be incorporated into the protective enclosure. Conversely, choosing or identifying the proper regional location to retrofit an empty space or void into CA helmet comfort liner of a CA helmet may be performed with assessing player factors. Such assessment of the player factors may allow the manufacturer of the ECM helmet to predetermine the best regional location for a protective enclosure to be secured. The decision to secure in the selected desired location may enhance the impact protection by incorporating impact mitigation structures into the protective enclosure or it may be to a desired regional location where impact performance may not be affected (the addition of such impact mitigation structures may be optional).
At least one of the various player factors or a combination of two or more player factors revealed in the 2017 NFL Video Review Study may be considered, the disclosure of which is incorporated by reference herein in its entirety. The 2017 NFL Video Review Study analyzed reported concussions sustained by football players in the NFL pre-season, regular season, and post-season games during the 2015 and 2016 season. The video review summarized that there were various player factors that were evident that may provide opportunities to enhance the safety and performance of a helmet. Such player factors may include, but not limited to, source of impact, angle or vector of impact, player activity type, play type, player position, location of impact, angle of impact, severity of impact, frequency of impacts, and/or any combination thereof.
For example, the NFL study video review revealed that the side of the helmet is the regional location most commonly associated with concussion causing impacts. However, other regional locations, such as the front 210, back-upper 270, back-lower 260, right-upper side 280, right-lower side 250, left-upper side (not shown), left-lower side (not shown), ridge or top 200, jaw flap, ear flap, facemask-upper 220, facemask-central 230, facemask-side edge 240 and/or any combination thereof, may be considered. Understanding that the sides or the back of the helmet are more frequently associated with concussion-causing impacts allows the manufacturer to customized placement of a retrofitted chamber or pocket and/or an empty space or void, where a protective enclosure may be positioned.
The player factor assessment allows the specific identification of the regional location of where not to consider retrofitting a chamber or pocket. In other words, the user may identify a regional location that Is proximate to the area that receives the most impacts or identify a location with the least amount of impacts for the specific player (i.e., where impact performance of the helmet would unlikely be affected by placement of a chamber or pocket). Conversely, the assessment may reveal that it would be beneficial to place a protective enclosure incorporating supplemental impact mitigation structures to enhance the safety and performance to protect the player in a regional location that receives more impacts.

General Electronic Communications Modules (ECM)
As disclosed herein, it may be desirable to place an ECM into a protective enclosure and removably couple the protective enclosure to various regional locations within the CA helmet to allow quick removal and provide impact protection to the player. The CA helmet may be retrofitted to removably couple a protective enclosure. Retrofitting a CA helmet may use the methods disclosed herein to accommodate the protective enclosure. Retrofitting may include at least one of (1) removing a portion of a comfort liner assembly to create an empty void or space, which a protective enclosure is removably coupled onto the empty space or void; (2) removing a portion of an impact mitigation layer to create a chamber or pocket, which the protective enclosure can be removably coupled; and (3) removing at least a portion of a comfort liner assembly to create a pocket or chamber within the at least a portion of a comfort liner assembly to create a protective enclosure, and/or (4) removably coupling the at least a portion of the modified comfort liner assembly. Alternatively, any ECM can be placed directly within the CA helmet outer layer, impact mitigation layer, the comfort liner assembly, and/or any combination thereof.
An ECM may comprise one or a plurality of electronic modules. The electronic modules may comprise any electronic modules that are capable of communications, video or image displays, data processing, storing data, transmitting data and/or utility. Such electronic modules may include one or more of a heads-up displays (HUD), a head-mounted displays (HMD), computer processing units (CPUs), optical communication systems, radio communication systems (e.g., one-way communication and/or two-way communication systems), full duplex communication systems, half-duplex communication systems, tactile communication systems, digital communication systems, power supplies (non-rechargeable or rechargeable), speakers, projector unites, microphones, any portable electronic devices (e.g., mobile phones, tablets, laptops, e-readers, MP3 Player, personal digital assistants (PDA), etc.), and/or any combination thereof.
Example Embodiments—Heads-Up Display
A Heads-Up Display (HUD) may comprise one embodiment of an ECM. A HUD may be any transparent display and electronic equipment that presents data without requiring users or players to look away from (or only slightly alter a point of attention or focus from) their usual viewpoints. The HUD (e.g., the projection apparatus and associated components) disclosed herein may be integrated or retrofitted into a commercially available (CA) athletic helmet, which desirably operate to produce a heads-up display in the CA helmet by interacting with a protective visor positioned proximate to and/or within the face shield of the helmet to transmit and/or reflect the projected information to the eyes of the wearer.
Due to the plurality of the associated components within a HUD, it may be desirable to place the HUD within at least one protective enclosure, and removably couple it to various regional locations within the CA helmet. The CA helmet may be retrofitted using the methods disclosed herein to accommodate the protective enclosure. Retrofitting may include: (1) removing a portion of a comfort liner assembly to create an empty void or space, which a protective enclosure is removably coupled onto the empty space or void; (2) removing a portion of an impact mitigation layer to create a chamber or pocket, which the protective enclosure can be removably coupled; and (3) removing at least a portion of a comfort liner assembly to create a pocket or chamber within the at least a portion of a comfort liner assembly to create a protective enclosure, and/or (4) removably coupling the at least a portion of the modified comfort liner assembly. Alternatively, the HUD or any other ECM can be placed directly within the CA helmet outer layer, impact mitigation layer, the comfort liner assembly, and/or any combination thereof.
In one exemplary embodiment, a commercially available (CA) helmet 1010 may be retrofitted to include a HUD as shown in
In various exemplary embodiments, the protective visor can desirably function as a “combiner” or semi-reflective surface, allowing the virtual information to be projected on a transparent visor screen so that the information appears to be floating in space as a virtual image (including the presentation of two dimensional and/or three-dimensional images or other information, if desired). In other exemplary embodiments, the protective visor can display and/or transmit information to the eye of the wearer, while in still other exemplary embodiments, a projector or similar device could be provided that is capable of transmitting information directly to one or more eyes of the helmet wearer.
In various embodiments, the heads-up display within the helmet is designed to provide a display at a sufficiently high intensity such that it can be viewed with a neutral density (anti-glare) visor, which may have a transmission value of approximately 16 percent. However, a combiner could alternatively include a coating or otherwise possibly attenuate one or more signals within the particular waveband(s) to which it is tuned, especially where multiple combiners (i.e., holographic combiners) may be incorporated into a single display visor. Where such specialized tuning is utilized, the transmission value of the anti-glare visor within the selected waveband could be increased and/or decreased, as desired.
In various alternative arrangements, a protective football visor can comprise a transparent plastic or glass material having include a neutral-color, thin-film interference coating, which could desirably increase the reflectivity of the visor to 23% (and which in turn reduces the visible transmission through the combiner to 77%). The transmitted view will desirably be color-neutral, while the virtual display image could be almost any shade or color, including full-color images as well as monochromatic images such as those derived from a cathode-ray tube (CRT) or similar projector/transmitter (i.e., green, where the human eye can be most sensitive). To work effectively, information from the virtual image in head-up displays will desirably be visible in a variety of conditions—the display will desirably be sufficiently visible to contrast with the ground, the playing field, other players, the ball (i.e., the football) and/or the background sky in bright cloud, sunlight and/or artificial lighting conditions (i.e., during night games)—which may include dynamic changes of the color and/or intensity of the display to accommodate varying backgrounds during play.
Because weight and safety are of paramount importance for a protective visor in a helmet, the use of a plastic combiner visor may be particularly desirable. For example, a single-notch rugate filter on a polycarbonate football helmet visor for a helmet-mounted display can desirably provide an extremely rugged and useful HUD system, and the use of multiple-notch coatings for visors and plastic combiners are specifically contemplated herein. In various embodiments, dual-graded combiners for three-color displays could be incorporated in a helmet, including the employment of triple-notch graded rugate coatings in which the notch depth progressively decreases over the grade to become an antireflection coating. In various sports applications, a multiple-color display could potentially enable information and/or “warning” indicators to attract player attention sooner than a monochromatic display, including the use of narrow-bandwidth color light engines and multiple-notch combiners.
In various embodiments, the protective visor will desirably comprise an impact resilient plastic structure, which may be curved to follow the contours of the helmet and/or the facemask and/or the user's face. Alternatively, the protective visor may comprise a more flattened or gently curved planar structure, but the visor will desirably be positioned in a location relative to the helmet to desirably ensure that helmet impacts do not cause the visor to strike the player's face and/or features with excessive force. If desired, the visor may comprise a relative thick structure (i.e., greater than 0.25″ in thickness), which may be easier to shape and/or curve than thinner structures where the visor incorporates or comprises an Organic Light Emitting Diode OLED or similar screen.
In at least one exemplary embodiment, a HUD apparatus and associated components can include a protective visor positioned proximate to and/or within the face shield of the helmet, at least a portion of the protective visor comprising a transparent (OLED) display, which can optionally include a curved surface that approximates and/or mimics the curvature of the face shield and which could be attached to various locations on the face shield and/or helmet body. In various alternative embodiments, an OLED display could comprise the entire face shield of the helmet (if constructed of sufficiently strong and/or thick layers of material it may even replace and/or augment traditional facemask bars), which could include attachment points proximate to or within the face opening of the helmet. In at least one additional alternative embodiment, the OLED display could encompass more than just the face opening of the helmet, which could include an OLED display which extends and/or wraps around some portion and/or all of the wearer's head, potentially including a helmet design including an outer OLED display surface forming the outer surface of the helmet, with a transparent “window” portion in the OLED display that accommodates the athlete's face (i.e., to allow the athlete to see through the transparent “window”) with the remainder of the helmet surface available for graphics and/or other visuals (i.e., to present advertising or sponsor visuals, or to identify radio communications capability and/or to indicate eligible football receivers on the field, etc.), in which these additional graphics and/or other visuals may or may not be visible to the helmet's wearer, and the “window” providing HUD information to the wearer as described herein.
Various aspects of the present invention, or any parts or functions thereof, may be implemented using hardware, software, firmware, non-transitory tangible computer readable or computer usable storage media having instructions stored thereon, or a combination thereof, and may be implemented in one or more computer systems or other processing systems. More particularly, embodiments of the present invention relate to systems and methods for wearable electronic devices, including devices and systems for presenting computer-generated sensory input via a HUD to an individual engaged in or observing an athletic activity, based on data related to the athletic activity. In various embodiments, an individual engaged in an athletic activity or an interested observer, such as a coach or fan, may desire to receive information about an athletic activity, including information about the individual's performance during the athletic activity.
In at least one exemplary embodiment, the helmet HUD may communicate with a wireless wide area network communications system such as that employed by mobile telephones. For example, a wireless wide area network communication system may include a plurality of geographically distributed communication towers and base station systems. Communication towers may include one or more antennae supporting long-range two-way radio frequency communication wireless devices, such as one or more helmet HUD systems. The radio frequency communication between antennae and the HUD may utilize radio frequency signals conforming to any known or future developed wireless protocol, for example, CDMA, GSM, EDGE, 3G, 4G, IEEE 802.x (e.g., IEEE 802.16 (WiMAX)), etc. The information transmitted over-the-air by the base station systems and the cellular communication towers to the HUD may be further transmitted to or received from one or more additional circuit-switched or packet-switched communication networks, including, for example, the Internet.
Example Embodiments—Placement of HUD within CA Helmet
In various embodiments, a HUD projection apparatus and associated components are disclosed that can be integrated into a protective CA helmet, such as a football helmet, by using at least one protective enclosure. One embodiment of the football helmet can include one or more removable protective enclosures that may be integrated within the impact mitigation layer of a CA helmet.
Alternatively, one or more components of the HUD systems described herein could be positioned in and/or located at non-CA helmet locations on a wearer's/player's body, such as battery packs, GPS sensors, antennas/transmitters and/or computing components being disposed and/or formed within protective pads (i.e., shoulder or shin or thigh pads) or other articles worn on other locations of the player's body. In such cases, there may be a need for additional wired and/or wireless connections between these components and the associated HUD or other components in the wearer's helmet
Such protective enclosures can be made of different structures, including a base, impact mitigation structures (such as buckling columns, laterally supported polygonal support structures such as hexagons, TPU cones, foam, elastomeric material, air, and/or any combination thereof), and/or a lid. Desirably, the protective enclosures can be house a variety of ECMs, such as including (but not limited to) components such as power supplies (i.e., battery packs), video and/or computing resources (i.e., microprocessors and/or memory resources), radio transmitters and/or receivers and/or camera and/or image projection devices. Where possible, the replacement components will desirably comprise low-profile, soft and/or flexible constituents and/or devices, such as flexible batteries (BrightVolt™ conformal batteries commercially available from BrightVolt of Redmond, Wash., USA) and/or similar components. Computing connections between the various components can be wired and/or wireless, including the use of Bluetooth TCP/IP, IEEE 802.16, Bluetooth low energy, ANT, ANT+ by Dynastream Innovations, BlueRobin, or similar communications technologies, if desired.
Where a protective enclosure incorporates a component of the HUD system, the replacement impact mitigation pad may optionally include one of more impact absorbing structures adjacent to the component as part of the pad body. For example, a replacement impact mitigation pad may incorporate a supplemental foam or reflex layer next positioned adjacent and/or next to the relatively harder HUD component, with the impact absorbing structure layer positioned between the wearer's head and the HUD component (to desirably protect the wearer from impact with the component, for example). In such a case, the foam or impact absorbing structure layer may be “stiffer” or provide additional resistance to impact to some degree than the remainder of the helmet protective layers (or the layer may be softer than surrounding helmet layers, in some embodiments). Alternatively, and/or in addition to the inner supplemental layer, the replacement impact mitigation pad may incorporate an outer supplemental foam or impact absorbing structure layer next to or adjacent to the relatively harder HUD component, with the impact absorbing structure layer positioned between the HUD component and the outer helmet layer (to desirably protect the component from external helmet impacts, for example). In such a case, this outer supplemental foam or impact absorbing structure layer may be “softer” or provide less resistance to impact to some degree than the remainder of the helmet protective layers (or this layer may be harder than surrounding layers, in some embodiments).
If desired, the protective enclosure can come equipped with removably coupled impact mitigation pad. Once the equipment manager designates the players that will carry the HUD and its associated components, the equipment manager may remove the impact mitigation pad and replace it with an ECM or a HUD and its associated components. The impact mitigation pad may be positioned over the ECM to act like a “lid” or cover. Then the protective enclosure can be re-inserted into the CA helmet in its designated locations.
As previously disclosed herein, the protective enclosure can comprise one or more segments of individual impact mitigation pads held within an outer shell, which can be placed in a designated impact mitigation layer cavity by sliding it from the edge of the helmet, placing it from the inner side of the helmet, or placing it within the impact mitigation layer through removal of a cavity “lid” or “cover”. In certain embodiments, the protective enclosure can be affixed to the surrounding structure/material with Velcro, mechanical fasteners, magnetic fasteners or slid into place so that it is securely held.
In various embodiments, at least a portion of the impact mitigation layer, at least a portion of the comfort liner assembly, or another helmet component could be removed and replaced by one or more ECMs. For example, a replaceable protective enclosure could include a portion that is adjacent to and/or which replaces a portion of an outer structure or outer layer of the CA helmet. For example, an occipital pad on the rear of a helmet may include a camera or other component which extends outside of and/or through an opening in the outer helmet body or outer layer (or which abuts the surface of the CA helmet, but does not extend fully therethrough). Such a camera could be extremely useful to the wearer to monitor “blind spots” around the player, such as rearward facing activities and/or the player's “blindside,” which could include a live feed to the HUD helmet display of the activity occurring rearward of the helmet. Currently, it is common practice for receivers and other players on the field to periodically watch the large stadium displays (i.e., the “Jumbotron”) during breakaway running to monitor pursuit activities by players behind them—a practice which could easily be duplicated on an individual basis using various components with the present HUD system.
For example,
The various embodiments described herein will desirably provide a player with a seamless experience on the field, and obviate the player's need to look away from a specific area in the field of activity in order to view an informational output (e.g., a visual indicator of the individual's heart rate or the speed of a ball kicked by the individual), which desirably maintains a proper level of attention, awareness, and concentration by the player on the athletic activity. In the context of an ongoing competitive session (e.g. a football or soccer match), this prevents a drop in the individual's performance during the inattentive moment and/or possible risk of injury to a distracted individual. Even in the context of a more informal non-competitive training session (e.g. conducting football or soccer drills), the distraction from having to look away from the individual's usual viewpoint can slowdown and therefore lengthen the training session and/or “pull” the individual out of their training “flow,” possibly reducing the overall effectiveness of the training session. Desirably, the HUD systems and associated components described in various embodiments of the invention may superimpose graphics, audio, and other sensory enhancements over a real-world environment, most desirably in real time. Such HUD systems may incorporate display technology that is capable of projecting one or more images in a way that makes them visible and overlaid on top of the individual's “real world” view of their environment.
In various exemplary embodiments, a helmet can include a protective polycarbonate or other plastic visor positioned within a “face opening” of the helmet, with the visor desirably functioning as a “combiner” or semi-reflective surface, allowing virtual information to be projected and/or reflected on the transparent visor screen so that the information appears to the wearer to be floating in space as a virtual image (see
As another alternative, the protective visor could alternatively display and/or transmit information to the eye(s) of the wearer (i.e., via an OLED visor), which may not require the use of a separate projector or similar device. For example, a HUD system in a CA helmet could include a combiner and an information generating device or other processing resources, wherein the image is produced directly in the combiner. The combiner can comprise, e.g., a liquid crystal display (LCD), a light-emitting diode (LED) display, or an organic light-emitting diode (OLED) display, optical waveguide, an electro-optical medium, or some other suitable medium for producing an image, which in various embodiments would desirably include a transparent portion of the display to allow the wearer to perceive the surrounding environment and field of play therethrough. Similar to the other combiner embodiments described herein, the size, shape, and placement of the combiner and related components described herein relative to the remaining helmet components can vary, as desired, including having a display size that can alter in size and/or location.
In various embodiments, a projector 1020, projector clips 1040 or similar device can be positioned within the helmet (see
In various embodiments, a power supply or power source such as a battery pack or similar component can be provided that fits within a space within the helmet or within a protective enclosure, such as a space vacated by one or more of the previously noted removable impact mitigation pads in the helmet. The power source may be built into the HUD or removable from the HUD, and may be rechargeable or non-rechargeable. In one embodiment, the HUD may be repowered by replacing one power source with another power source. In another embodiment, the power source may be recharged by a cable attached to a charging source, such as a universal serial bus (“USB”) FireWire, Ethernet, Thunderbolt, or headphone cable, including a cable attached to a personal computer or other power supply. In yet another embodiment, the power source may be recharged by inductive charging, wherein an electromagnetic field is used to transfer energy from an inductive charger to the power source when the two are brought in close proximity but need not be plugged into one another via a cable. In some embodiments, a docking station may be used to facilitate charging.
Desirably, the power supply will include one or more wired connections that can be connected to other components, which may include wires positioned within the inner surface of the helmet, within the impact absorbing or impact absorbing structure layer and/or between pads or other impact layers. For example,
Where the impact absorbing structures of the helmet incorporate impact absorbing structure layers including buckling structures and/or similar filament-based impact absorbing structures (including laterally-supported filaments and/or polygonal support structures such as hexagonal impact structures), these wires can easily be routed through and/or around the individual filaments/structures in the impact absorbing structure layer without significantly impacting the performance of such impact absorbing structures, greatly simplifying the assembly and maintenance of the HUD system. Alternatively, various wires and/or other connections may extend and/or be positioned outside of the helmet, or various combinations thereof. In various embodiments, removeable and/or replaceable wiring connections could be provided for a variety of components, including between various modular helmet components.
In various embodiments, a computing component will be provided that comprises a video and/or computer processing unit, which desirably provides image information to the projector, OLED screen and/or other display device within the helmet. If desired, the computing component could comprise a “static” unit that contains stored information that is processed and/or transmitted to the display unit in a variety of ways, or the computing component could comprise an interactive or dynamic computer and/or video processing unit that could be capable of processing external inputs and/or modifying the displayed information based on a variety of external and/or user controlled factors. For example, the computing component could include a memory component wherein a series of pre-loaded initial plays are loaded for the beginning of a football game, with each of these plays presented to the player through the display device during the “huddles” between plays. The memory of the HUD may similarly be adapted to store application program instructions and/or to store athletic activity data from player activity during the football game. In one embodiment, the memory may store raw data, recorded data, and/or calculated data. In some embodiments, the memory may act as a data storage buffer. The memory may include both read only memory and random access memory and may further include memory cards or other removable storage devices.
In various embodiments, the computing component could include a connection to one or more external inputs, which could include environmental and/or player inputs that could be processed to alter some or all of the presentation on the display device. For example, the HUD system or other device could provide the user with a “projection keyboard” or similar display feature, with icons or letters (or other selections) being projected onto the HUD display and/or other surface (including projections appearing to be on one or more “virtual surfaces” within the HUD display. The system could further incorporate sensors to determine selection or “activation” of the icon or letter, including visual or other sensors to determine the location of a wearer's fingers. Alternatively, the HUD display could include a touch-sensitive inner and/or outer surface to accommodate selection and/or activation by a wearer.
In at least one exemplary embodiment, a HUD system could display a series of selectable icons on an inner surface of the protective visor (which would desirably be visible to the wearer of the helmet), and the wearer could touch or position a finger (or other extremity) proximate to at least one icon at a corresponding location outside of the protective visor. Desirably, the HUD system could include a camera or other sensor that can interpret the wearer's outside finger movement as selecting or otherwise activating the icon in a specific manner (including gesture based movement such as curling or “scrolling” with one's finger to scroll through a series of selectable icons, or “sweeping” of a hand to either side to change a HUD display screen). In various embodiments, the icon could appear to be floating in the virtual environment, while in other embodiments the HUD system may “link” a specific icon to the outside environment, where movement of the user's head would not affect the position of the icon relative to the surrounding environment (i.e., the icon could appear to be on the playing field or ball, with the system maintaining the icon in a specific location in the environment, even where the helmet and visor were moved and/or rotated).
In even further embodiments, a wired and/or wireless receiving/transmitting device could be attached or otherwise linked to the computing component, with data transmission to and/or from the computing component and one or more external sources. For example, communication may also occur between the HUD system, and one or more other computing devices such as other Helmet HUD systems worn by other players, a server, a mobile phone, a body-mounted device, a ball-mounted device, and/or a coach device via a network. In at least one embodiment, the network can be a local network located within a sports stadium, while in another embodiment it may be the Internet. The Internet is a worldwide collection of servers, routers, switches and transmission lines that employ the Internet Protocol (TCP/IP) to communicate data. The network may also be employed for communication between any two or more of the HUD systems, server, a mobile phone, a body-mounted device, a ball-mounted device, and/or a coach device.
In various embodiments, the HUD system could include a communication device or radio to communicate via, e.g., a wireless network or a wired network, with other components, including other helmet components, other helmet systems and/or wearable components on the wearer or other team members. The wireless network could operate using, e.g., Bluetooth, WiFi (IEEE 802.11) or some other wireless protocol. In some embodiments, the HUD system could incorporate one or more other additional sensors. For example, in some embodiments, the HUD may include one or more of an acceleration sensor, a heart rate sensor, a magnetic field sensor, a thermometer, an angular momentum sensor (e.g., a gyroscope), and a positioning system receiver. In other embodiments, one or more of these sensors may be omitted, or one or more additional sensors may be added. If desired, the HUD could provide the wearer and/or an external monitoring station (i.e., a coach's or team doctor's station) with user-specific physical information such as player body temperature, blood O2 saturation, heart rate, skin conductivity and/or blood pressure, as well as more generalized information such as player direction, speed, orientation and/or acceleration/deceleration during movement and/or tackling. Various embodiments could also include eye monitoring and/or tracking systems, including systems capable of detecting abnormal eye tracking by a player, which may be an indication of a potential concussion or other health issue requiring further monitoring and assessment. Such information could be provided real-time to a player's sideline coaches, or the HUD system could provide such information after an active play has ceased (i.e., between football “downs,” for example). Such information might be extremely useful to the coaches and/or team doctor in order to make player condition assessments before starting the next play on the field.
In one exemplary embodiment, a football helmet will incorporate a head-up display (HUD) for the wearer. In some embodiments, the HUD includes a projector, a combiner, and an information generating system or other computing system. The projector can be, e.g., an LED array, an LCD display, a laser, a combination LED/LCD system, or some other suitable projector system. In this embodiment, the projector projects an image onto the combiner. The image can be in the form of text, graphics, video, etc. The projector receives image information, e.g., in the form of a digital signal, from information generating device. The information generating device generates and/or processes the image based on information received from a computer system or from an external source (i.e., via radio from an external information source). This information can include a wide variety of topics, including current weather conditions on the field, opposing and/or same team player identification, play choices and/or running patterns, play information (i.e., game time remaining, play countdown clock, down, ball position and/or remaining yards for first down), etc. In some embodiments, the projector and information generating device can be integrated into a single physical unit. In some embodiments, the computer system can generate and/or process image(s) and transmit the image information directly to projector, which could include and/or be connected to a wireless communication device.
In various embodiments, the combiner will receive image information, e.g., in the form a digital signal, from the computing component and/or some other information generating device, which generates and/or processes the image based on information received therefrom. In some embodiments, the combiner and the information generating device could be integrated into a single physical unit. In some embodiments, the combiner and projection lens could be integrated into a single physical unit. In some other embodiments, the combiner, information generating device, and projector could be integrated into a single physical unit. In some embodiments, the computer system may generate and/or process the image and transmit the image information directly to combiner, which can include or is connected to a wireless communication device. In some embodiments, a combination camera and projector may be provided in the helmet, which may be similar to the OmniTouch camera/projector system developed by Carnegie Mellon University and Microsoft research.
In some embodiments, the combiner will desirably collimate the reflected image such that the projected image appears to be at a desired distance from the wearer, such as (1) adjacent to and/or next to the wearer's face or body, (2) at approximately five feet from the wearer, (3) at approximately 10 feet from the wearer, (4) at approximately 10 yards from the wearer, (5) at approximately 25 yards from the wearer, (6) at approximately 50 yards from the wearer, and/or (7) at optical infinity. Desirably, this collimation distance may coincide with the wearer's current activity focus, to obviate a need for the wearer to refocus to see both the external field activity and the projected image—especially during active play. If desired, the HUD system could include one or more cameras or other systems that could monitor player focus and modify the collimation distance to approximate the player's current focal length and/or attention location, and/or the system could remove the information from the display screen when the player focuses away from a desired “distance” and/or location area on the display visor (i.e., removing displayed information from the visor while a receiver is attempting to catch a thrown football).
In some embodiments, the combiner 134 is an appropriate transparent material, e.g., a curved and/or flattened piece of plastic and/or glass, that is angled and/or positioned such that the projected image from the projector is reflected to the wearer. In some embodiments, the mounting of the projector and/or combiner (i.e., visor) to the football helmet could be manually and/or automatically adjustable, such that the angle of reflection could potentially be adjusted by the wearer and/or equipment technician (or potentially accomplished by the system with verbal or other input from the user), as desired.
The size, shape, and placement of the protective visor/combiner relative to the one or more projection lens(es) can vary, as desired. For example,
In various embodiments, the image window on the visor, i.e. the window in which actual information is displayed, can be sized and/or located as desired, including the provision of different amounts and/or locations of information depending upon a specific stage of play. For example, during play an image window can be displayed in a corner and/or along an edge of the visor so that the player is not distracted, but still has the information available, if desired. When the play has ended, or during other activity on the field, the image window can be displayed larger on the visor. The HUD system can be configured such that the image is automatically resized based on helmet movement and/or in response to an external and/or user activated system, which potentially indicates when an active play is in process. Alternately, or in addition, the HUD system can be configured such that the resizing and/or relocation of images is a manual operation by the wearer.
In various embodiments, the image information seen by the wearer can be configurable. For example, the computer system and/or other system components can be configured with different “views” or image screens that the wearer can select. For example, various information can be presented to the wearer using several image screens or “views,” which can include a variety of potential player input techniques to allow the player to “scroll” through individual views. For example, a first view could represent field conditions surrounding the player, including field temperature, wind speed and direction, relative humidity and/or air pressure and play clock time remaining. A second view could provide a list of potential plays to be “called” on the field, which could include a list of cues for audible calls by the team leader to modify a currently called play to accommodate an offensive or defensive repositioning by the opposing team. A third view could be activated by motion of the player (i.e., detected by an accelerometer in the helmet) and/or upon “snapping” of the ball (i.e., detected by an external signal, a visual cue from a helmet camera and/or by an aural signal), which could provide live action views of the surrounding area (i.e., an external view from a rearward facing camera) as well as play and player information (i.e., opposing players could be highlighted in red, with a potential “run route” for one or more players highlighted in green). The views could be customized to meet an individual player's needs, which may be customizable based on the player's position and/or the current game situation (i.e., accelerated presentation during a two-minute drill), or on some other basis. In addition, the views could be customized for each player, which could include a player identifying himself or herself by, e.g., logging into the computer system, by using a token such as, e.g., a RFID tag, or by some other means, wherein the computer system could display a set of “views” that are specific to the player, e.g., based on the player's preferences, experience level, etc.
In various embodiments, the player can turn the HUD on and off and/or scroll through the “views” using a variety of controls on the football helmet, which could include touch sensitive locations and/or touch screen controls on the inside and/or outside of the helmet, the inside and/or outside of the helmet visor, the facemask and/or the chin strap. Alternatively, or in addition, the player might control the HUD using voice or movement commands, wherein the system could include a microphone system, camera and/or accelerometer that picks up audio or physical commands from the wearer. The microphone system or other sensors can then relay the audio commands to the computer system, which can interpret the commands and send the appropriate instructions and information to the computing system. The computing system or other information generating device will then control projector and/or combiner based on the received information and instructions. For example, a player could say “SHOW CURRENT CONDITIONS” and the system will display the surrounding environmental conditions (as previous identified). Other voice commands can be used to allow the user to display the desired information. These voice commands can be used, prior to, during or after the completion of an active play. In addition to the commands discussed above, the player might be able to adjust the size and location of the image window, the brightness of the image display, the color of the image display, etc. In some embodiments, the player may wish to control the opacity of the image to make the image more or less transparent, e.g., from nearly 100% transparent to 100% opaque, while in other embodiments, one or more of these parameters can be adjusted automatically by the computing system based on the current play activity and/or the level of ambient light.
Where incorporated into a HUD system, a microphone may include any suitable audio recording component. The microphone may be used to receive voice commands from the individual to control the HUD, to receive voice notes, to conduct telephone calls or other communications, or to capture other relevant sounds during the course of an athletic activity such as the sound of the athlete's helmet contacting another player's helmet, the sound of a coach calling out an instruction to the individual, or the sound of a referee's whistle blowing.
In various embodiments, an individual can be engaged in the sport of football while wearing a protective helmet such as described herein. While embodiments of the present invention are primarily discussed with respect to the sport of football, the athletic activity HUD systems and methods described herein may be suitable for use by individuals or other interested individuals for team or individual athletic activities and for competitive and informal training sessions in other sports as well. For example, the athletic activity HUD systems and methods described herein according to embodiments of the present invention may be suitable for use by individuals engaged in athletic activities such as baseball, basketball, bowling, boxing, cricket, cycling, golf, hockey, lacrosse, soccer, rowing, rugby, running, skateboarding, skiing, snowboarding, surfing, swimming, table tennis, tennis, or volleyball, or during training sessions related thereto. In a similar manner, alternative embodiments of the inventions described herein could be employed for impact-related uses, such as protective equipment for law enforcement and/or soldiers in combat environments.
In various embodiments, the output of an exemplary HUD may include both a visual display output along with non-visual information such as audio (e.g. via a speaker) and/or tactile (e.g. vibration) output, in addition to or instead of visual display output.
In various embodiments, a video camera or other suitable video recording component, such as a digital video camera, can be incorporated into the HUD system. In some embodiments, the video camera may be configured and oriented such that the video camera may view the environment in front of the helmet (i.e., through an opening in the front of the helmet) to perceive and record a “first person” view of what the individual wearing the HUD system “sees” while engaged in their athletic activity. Any video recorded may be played back to the individual or other interested individual in real time or after the recorded event. In some embodiments, the HUD system may playback a recorded video that is annotated with other visual images, such as the images discussed throughout as being potentially displayed in the projected image field. In one embodiment, first person recorded video may be played back to the individual wearing the HUD system such that the first person recorded video takes up the individual's entire field of view. In this sense, the first person recorded video may provide a “virtual reality” experience to the individual. In another embodiment, the first person recorded video may be played back to the individual wearing the HUD system such that the first person recorded video takes up less than the individual's entire field of view. For example, the first person recorded video may be displayed in one corner of the individual's field of view (i.e., a picture-in-picture view) so that the individual may view the video or shift their attention to other real-world items in their field of view.
Incorporating a video camera into an embodiment of a helmet HUD may provide the HUD with additional capabilities. For example, the HUDs according to various embodiments of the present invention incorporating a video camera may be used to determine the orientation of the individual's body to the ball or other playing object, determine the orientation of the playing object to the goal (i.e. determine when a touchdown or other goal is scored based on a recorded video image of the ball entering the end zone or goal), determine the flight speed, rotation rate and/or rotation speed of the ball, determine the number of ball touches or out-of-bounds location, or even trigger the taking of a still photo or video clip by the HUD system based on a determination of a ball impact.
In various embodiments, a HUD system can be provided to non-players, such as to a coach, a referee or umpire, a team physician and/or a sports fans. A coach's HUD may allow the coach to communicate with one or more individuals during an activity, such as players also equipped with HUDs. Communication may include audio (e.g. voice) communication and/or visual (e.g. text messages, images, or videos) communication. In one embodiment, the coach's HUD may present the coach with a visual illustration of a desired play, formation, player route, or other visual information about desired player movement during the activity. And in some embodiments, the system could be adapted such that one or more players (e.g. all players, a team captain, or a player currently in possession of the ball) can simultaneously view the same visual information about desired player movement on their own HUD system that the coach is viewing in his HUD system. In this way, a coach and his players can share information and strategize in real time during an athletic activity about desired player movements without having to huddle together during a stoppage of play (e.g. a timeout).
In various embodiments, a helmet mounted HUD system can also be a useful tool for a variety of “augmented reality” applications, including for use by players during a football practice event. In its simplest terms, augmented reality presents computer-generated sensory input to a user, including superimposed graphics, audio, haptic feedback, or other sensory enhancements, that provide information about the environment and its objects in the context of a real-world environment. For example, American football fans are accustomed to the presence of a super-imposed “first-down” line on televised American football games, which could similarly be provided to a player through a helmet HUD system on the actual field of play. Moreover, the use of unique symbols and/or color coding schemes that can be virtually superimposed on actual objects (as seen through the helmet HUD) has the potential to provide significantly more immediately useful information to the player about the playing field and conditions, teammates and/or opposing players. For example, various colors such as red, yellow, blue and/or green (or even multiple colors or flashing indicators) can be superimposed on real objects and/or other players via the combiner to indicate potential conditions, such as identifying the ball carrier, eligible receivers, out-of-bounds lines and/or first down markers.
